However, all attempts to blend general relativity and quantum physics necessarily introduce deviations from Einstein's theory. Therefore, Einstein's gravity cannot be the ultimate theory of gravity.

General relativity has withstood perhaps its toughest challenge to date. The theory, which Albert Einstein published in 1916, revolutionized our understanding of physics and the cosmos.

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...

In pure general relativity, with no other modifications or considerations of other physics, they remain black for eternity. Once one forms, it will just hang out there, being a black hole, forever.

General relativity has withstood perhaps its toughest challenge to date. The theory, which Albert Einstein published in 1916, revolutionized our understanding of physics and the cosmos.

When the first-ever image of a black hole was released in April 2019, it marked a powerful confirmation of Albert Einstein’s theory of gravity, or general relativity. The theory not only ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...

The first image of a black hole, captured in 2019, has revealed more support for Albert Einstein’s theory of general relativity. The new finding has suggested his theory is now 500 times harder ...

For the first time, a mathematical framework proves that Einstein’s theory of general relativity, which explains the relationship between space, time, and gravity, is in alignment with quantum ...

By the end of this video, you'll understand how general relativity completely changes our perspective on gravity, revealing it not as a force but as a result of the curvature of space-time.

Special relativity and Lorentz transformations; Scalar and electromagnetic fields; Curved spacetime and the metric tensor; The equivalence principle; Geodesics, covariant derivatives, and Killing ...

When general relativity is included in large-scale simulations of the cosmic structure of the Universe, relativistic effects turn out to be small but measurable, thus providing tests for models of ...
